Yes, in the controller:
user_plant_widget = SingleSelectField('plants', options=[]) # put
default/dummy options in
@expose('project.templates.user_plant'
def plant(self, user):
options = qlfOptions.getUserPlantOptions(user)
return dict(widget=user_plant_widget,
params=dict(options=options))
And somewhere in user_plant.kid:
...
${widget.display(**params)}
...
That will pass the options in when the page is rendered for the given
user.
If your SingleSelectField is part of a form or other compound widget,
you'll need to pass the options differently. I can't remember the
syntax exactly for TG widgets, but for ToscaWidgets I think it would
be (untested, from memory)
@expose('project.templates.user_plant'
def plant(self, user):
options = qlfOptions.getUserPlantOptions(user)
child_args = dict(plants=dict(options=options)) # child named
'plants' gets the keyword argument 'options'
return dict(widget=user_plant_widget,
params=dict(child_args=child_args))
The pattern for TG widgets is similar, but it's not "child_args", its
something else, and I think the structure might be different.
Sorry, can't remember any docs on it, I had to grok the source to
figure it out back then. I've been using toscawidgets since they were
released, much better IMO.
